STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters fatnt No. 295,484, dated March 18, 1884.

Application filed August 23, 1883. (No model.)

To all whom, zt/mag! concern/.-

Be it known that I, DUANEH. CHURCH, of Valtham, in the county o'f Middlesex and State of Massachusetts, have invented certain Improvements in 'Pendant Vinding and Setting Vatches, of which the following is a specification.

rIhis invention has for its object to provide improved means for making the hand-setting train of a pendant winding and setting watch operative and inoperative by the movement of the yoke which is pivoted upon the center of the crown-wheel, whereby motion is imparted from the stem either to the setting or winding wheels.

IIhe invention consists in adapting the intermediate setting-wheel to move in and out in a direction at right angles to its plane of rotation, instead of moving` with the yoke parallel with said plane, and in the provision of means wh creby said intermediate wheel is normally held with a yieldingpressure against the yoke and in engagement with the minutewlieel of the hand-setting train when the yoke is in position for hand-setting, and is forced inwardly out of engagement with said wheel by the movement ot' the yoke to position for winding, as I will now proceed to describe.

Cf the accompanying drawings, forming a part .of this specification, Figure l represents a side view of a portion of a watch-plate provided with my improvement, the yoke being in position for setting. Fig. 2 represents a section on line .fr as, Fig. l. Fig. 3 represents a view similar to Fig. l, showing the yoke in position for winding. Fig. 4 represents a section on line y y, Fig. 3. Fig. 5 represents a view of the opposite side ofthe plate. Fig. 6 represents a side viewof a portion of the plate, showing a lever projecting through the case as a means for shifting the yoke.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a portion of the plate of a watch, and b a portion of the case having the pendant c.

d represents the windingarbor or pipe-key, adapted to rotate in the pendant c, and provided with the usual bevel-pinion, e, which meshes with the crown-wheelf, on which the yokeg is pivot-ed. Said yoke is adapted to oscillate,as usual, on the wheel f, and carries at one end the usual intermediate winding-wheel, h, which is always in engagement with the wheel j', and is moved by the yoke into and out of engagement with the mai nspring winding-wheel.

t' j represent, respectively,the cannon-pinion and minute-wheel of the hand-setting train, said wheels being journaled on arbors affixed to the watch-plate.

The construction thus far described is the common one, and forms no part ofmyinvention.

k represents the intermediate wheel through which motion is communicated from the crownwheel f to the minute-wheel j.

In carrying out myinvention, I provide the plate c with a cavity, Z, under said intermediate wheel ,and with a iiXed arbor, m, projecting from said cavity. The intermediate wheel, 7c,rotates on said arbor, and is adapted to slide thereon at right angles to its plane of rotation. The cavity lis of sufficient depth to permit the intermediate wheel, k, to sink below the plane of the minute-wheel, as shown in Fig. 4, and thus become disconnected therefrom by a movement at right angles to the plane of rotation of said wheels. The intermediate wheel, 7c, is held with a yielding pressure against the yoke, and is normally raised from the bottom of the cavity Z into the plane of the minutewheel j by a spring, m', as shown in Fig. 2,. The outer side of the intermediate wheel, k, is provided with a conical projection, n, and the yoke is provided with a corresponding recess or'orice, o, which coincides with the projection 'n and permits the intermediate wheel, 7c, to be forced outwardlyby the spring only when the yoke is in position forsetting, as shown in Figs. 1 and 2. When the yoke is moved to position for winding, as shown in Fig. 3, the orifice 0 is moved away from the projection n, and the inner surface of the yoke bearing against said projection forces the intermediate wheel into the cavityl and disengages it from the minute-wheel j, as shown in Fig. 4. It will be seen that by adapting the yoke to move the intermediate wheel, 7c, at right angles to the plane of its rotation in separating it from the minute-wheel, there is no tendency to rotate the minute-wheel, and thus move thehands by the separation of said wheels. Vhen the intermediate wheel is supported by the yoke,

and moved thereby in a direction parallel to or in line with the plane ot' its rotation, as usual, it is liable to partially rotate the minute-wheel in being separated trom it, thus necessitating the readjustment of the hands. rllhe yoke may be shifted i'rom one position to the other by an endwise movement oi' the windingarbor, or, it' said arbor is not movable endwise, by means ot' a lever, s, pivoted to the ease and having one arm bearing against a proj eetion, s', on the yoke, and another arm, si, projecting through the margin ofthe ease, as shown in Fig. (i. lVhen the arm s is pulled outwardly, the arm s pushes the yoke 'l'roin the winding to the setting position, and when the arm 3* is pushed inwardly a spring, if, t'orees the `yoke into winding position.

l am aware that it is not new to make the intermediate wheel, 7.1, movable in a direction at right angles with the plane ot' its rotation ior the purpose ot' engaging it with and disenw gaging it i'roin the minute-wheel without displacing the latter; hence l do not elaim this feature.

I elaim-' l. In a pendant winding and setting vfatoh, the Combination,with the hand-setting wheels y j and erown-wheel j", rotated bythe windingarbor, ot' the intermediate winding-wheel adapted to move on a fixed stud or arbor in a direction at right angles with the plane of its rotation, into and out ol" engagement with its (3o-operating wheels, a spring adapted to move the intermediate wheel outwardly i nto engagement with said eo-operating` wheels, and the yoke bea ring upon the intermediate wheel and adapted to eontrol the position thereof', as set t'orth.

2. In a pendant winding and setting watch, the combination,with the hand-setting wheels ij and tho crown-wheel j', rotated by thekeypipe, oi' the intermediate hand-setting wheel, lf, adapted to move on its supporting pin or arbor in a direct-ion at right angles with the plane ot' its rotation, the winding-wheel earrying yoke g, pivoted on the erown-wheel, anda spring which presses the hand-setting wheel 7.: outwardlyr against the yoke, said yoke and wheel being provided, respectively, with an oriiee and a proj eetion,wl1ereby when the yoke is in its liaii lsetting position the spring is allowed to `torce the wheel l: outwardly into en` gageinent with the Crown-wheel and minutewheel, and when the yoke is 'in its winding position the wheel 7.: is forced inwardly out ot' engagement with said erown and minute wheels, as set forth.

In testimony whereof l have signed my naine to this speein'eation, in the presence ot`twosubseribing witnesses, this 16th day of JAugust, 188:3.
